Description

Composition for prevention of hair loss or improvement of hair growth}

The present invention relates to a composition for preventing hair loss or promoting hair growth, and specifically, by containing fucosyllactose as an active ingredient, it promotes hair growth by inducing proliferation of dermal papilla cells and inhibits the activity of 5-alpha-reductase. The present invention relates to a composition for preventing hair loss or stimulating hair growth, which has an excellent effect of inhibiting the production of hydrotestosterone and promoting the activation of the wint/beta-catenin signaling pathway.

In addition to the simple function of biologically protecting the scalp, hair has been considered important as a means of expressing beauty and individuality in terms of beauty. In particular, in a modern society that values beauty, hair occupies the most important part in satisfying the desire for individual expression regardless of age or gender.

In recent years, not only male pattern baldness, but also a change in dietary habits and an increase in stress caused by social environments have led to an increase in the number of female hair loss populations, and their age is also decreasing regardless of age or gender. Moreover, in recent years, as the regulation or restriction of internal and external activities has been followed by the prolonged corona pandemic, the number of hair loss population due to increased stress, lack of exercise, irregular lifestyle, etc. is rapidly increasing.

There are about 100,000 to 150,000 hairs in the human body, and each hair has a different cycle and repeats growth and shedding through anagen, catagen, and telogen. This hair growth cycle is repeated over 3 to 6 years. As a result, it is a natural phenomenon that about 50 to 70 hairs fall out per day, but if the number of hairs that fall out exceeds 100, it is likely to be a symptom of hair loss.

In general, 'alopecia' refers to an increase in the number of abnormally falling hairs due to a decrease in the proportion of hair in the growth phase and an increase in hair in the catagen or telogen phase during this cycle. Alopecia, in which hair is lost from the scalp, is caused by various factors, and is usually divided into congenital genetic predisposition and acquired alopecia formed by receiving other environments. Currently, the causes of hair loss include internal factors such as the action of male hormones or external factors such as mental stress in daily life and accumulation of lipid peroxide in the scalp. there is.

Specifically, in terms of the hair growth cycle, alopecia refers to an increase in the number of hairs that fall out abnormally due to a shortened hair growth rate in the hair growth cycle and an increased number of hairs in the catagen or telogen phase. Hair loss is a normal phenomenon, but normal people have a lot of hair in the growth phase, whereas people with alopecia have a lot of hair in the resting phase. In other words, the characteristic of people exhibiting alopecia is miniaturization of the hair. As hair loss progresses, the period of the growth phase is shortened, the transition to the catagen phase and the telogen phase is promoted, and the volume of the subsequent hair dermal papilla is reduced, so the hair follicles are gradually miniaturized. Therefore, for the treatment of hair loss, it can be said that it is more preferable to make hair follicles in the telogen phase go quickly to the anagen phase and to increase the shortened anagen phase.

Hair loss prevention agents that can improve or treat alopecia that are currently widely used include minoxidil and oral finasteride, which are external skin preparations approved by the US Food and Drug Administration (FDA), and approved by the Ministry of Food and Drug Safety (MFDS) in Korea. There is an oral dutasteride that has been received. Minoxidil, which has been used as a treatment for hypertension, has been known to promote hair growth through a mechanism that expands blood vessels through hyperpolarization of cell membranes and supplies nutrients to hair follicles, but recent studies have shown that minoxidil promotes hair growth by acting directly on hair follicle cells. It has been reported to activate the signaling pathway of Wnt/β-catenin, which is a mechanism. Finasteride is the ingredient name of Propecia, which was developed as a treatment for benign prostatic hyperplasia and then introduced to the treatment of alopecia. It is known to inhibit the production of DHT, which causes hair loss. However, hair loss inhibitors such as minoxidil, finasteride, dutasteride, etc. show a temporary great effect in terms of efficacy, but the fact is that the effect varies greatly between individuals, and the effect disappears immediately when discontinued, and various dermatitis or As many side effects, such as loss of sexual desire and induction of gynecomastia, are concerned, it is difficult to maintain these effects for a long period of time.

Human milk oligosaccharides (hereinafter referred to as HMOs) having more than 200 unique structures are present in a significantly higher concentration (5-15 g/L) than milk of other mammals. HMO is a prebiotic effect that helps the growth of lactic acid bacteria in the intestine, inhibits the growth of harmful microorganisms in the intestine and enriches beneficial microorganisms. In addition, it plays a role in preventing several pathogens, including viruses, bacteria, and protozoa, from binding to glycoconjugate targets on the surface of epithelial cells. As such, HMOs are effective in preventing pathogen infection and regulating the immune system. It has functionality that provides various biological activities that affect human health.

Currently, about 200 different complex oligosaccharides have been found in human milk, and among them, 137 oligosaccharides, including the three most abundant oligosaccharides, are fucosylated, and the ratio reaches about 77%. The rest of the oligosaccharides are mostly sialylated, with about 28% (39). Normal milk does not contain it, so it is currently getting a lot of attention. The most abundant fucosylated HMOs, 2-fucosyllactose and 3-fucosyllactose, are contained in human milk at 0.5-2 g/L.

Fucosylated HMOs are circulated throughout the body as well as the gastrointestinal tract to exert an effect, and it can be seen that they are detected in plasma and urine. In addition, fucosylated HMOs are known to be major HMOs involved in various biological activities, such as changing the immune response, controlling tumor metastasis, directly exhibiting bacteriostatic and antibacterial effects, and increasing resistance to immunity.

Recently, as it is known that fucosyllactose is the most abundant oligosaccharide contained in breast milk, it has attracted great attention as a material for infant formula and health functional food for the elderly and pharmaceuticals that can provide health benefits to both adults and infants.

Regarding the efficacy of the fucosyllactose, Republic of Korea Patent Registration No. 10-1972925 skin irritation relief effect, Registration Patent No. 10-2042967 registration effect skin aging improvement, Registration Patent No. 10-2302304 registration effect preventive effect of inflammatory skin disease, Patent Publication No. 10-2021-0005604 discloses the effect of preventing diseases caused by immune secretion, Patent Publication No. 10-2019-0045079 discloses the effect of preventing eye dryness, and Patent Publication No. 10-2019-0130720 discloses the effect of preventing stroke. However, no examples of using it for hair loss prevention or hair growth promoting efficacy have been known yet.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In general, the nomenclature used herein is one well known and commonly used in the art.

Hereinafter, the present invention will be described in more detail.

In the present invention, "fucosyllactose" is an oligosaccharide (HMO) contained in human milk, and human milk-derived fucosyllactose is used as a prebiotic for brain development and immune response control in the human body. It promotes the growth of useful microorganisms in the intestine, such as Lactobacillus and Bifidobacteria , and becomes a recognition material for receptors such as respiratory pathogens Pseudomonas aeruginosa , Clostridium , and Salmonella fyris , and inhibits their invasion competitively to inhibit their growth. It acts as a barrier and can be produced by the action of fucosyltransferase.

The HMO is D-glucose (Glc), D-galactose (Gal), N-acetylglucosamine (GlcNAc), L-fucose (Fuc) and sialic acid (Sia; N-acetyl neuraminic acid: Neu5Ac) It consists of The structure of HMO is so diverse and complex that about 200 isomers with different residues and glycosyl bonds can have different degrees of polymerization (DP 3-20).

The HMO is D-glucose (Glc), D-galactose (Gal), N-acetylglucosamine (GlcNAc), L-fucose (Fuc) and sialic acid (Sia; N-acetyl neuraminic acid: Neu5Ac) It consists of The structure of HMO is so diverse and complex that about 200 isomers with different residues and glycosyl bonds can have different degrees of polymerization (DP 3-20).

In addition, HMOs have several common structures, and most HMOs have lactose (Galbeta1-4Glc) residues at their reducing ends.

The above fucosyllactose refers to a three-carbon sugar in which fucose is added to lactose, and specifically, Gal of lactose is alpha-(2,3)- and alpha-(2,6)-bonded. sialylated in the form of 3-sialyllactose or 6-sialyllactose, respectively, or alpha-(1,2)- and alpha-(1,3)-linkages, respectively. It can be fucosylated in the form of 2-fucosyllactose or 3-fucosyllactose.

According to a preferred embodiment of the present invention, the fucosyllactose in the present invention is 2'-fucosyllactose (Fuc-alpha1,2-Gal-beta1,4-Glc) and 3-fucosyllactose (Gal-beta1 ,4-(Fuc-alpha1,3-)Glc).

In the present invention, there may be several methods for obtaining the fucosyllactose. For example, 2-fucosyllactose and 3-fucosyllactose may be obtained from the precursors through an enzyme synthesis method using a glycosyltransferase derived from a specific microorganism, but is not limited thereto.

The above fucosyllactose can be prepared by a known method or purchased and used prepared by a known method. It was performed using, and is represented by the following formulas 1 and 2.

Although many studies on the cause of hair loss or promoting hair growth are continuously and actively conducted, the exact biological mechanism related to hair loss is still very complicated.

Hair repeats the hair cycle of growth, catagen, rest, and growth, and alopecia refers to a state in which the resting period is long and the growth period is short. It has been believed that hair regeneration is almost impossible until now because hair follicles atrophy when the resting period is long, and most of the hair loss prevention agents currently on the market expect only the hair loss prevention effect of growing hair.

Hereinafter, the invention for preventing hair loss or promoting hair growth of the present invention will be described in detail.

In the present invention, "hair loss" refers to a state in which there is no hair in an area where hair should normally exist, and specifically means that the terminal hair (thick and black hair) of the scalp is lost, and various hair loss from slight thinning to complete baldness. appear in the form The cause of hair loss is not limited, but examples include hereditary androgenetic alopecia (baldness), alopecia areata, ringworm of the head (tinea capitis) caused by fungal infection, telogen effluvium, hair growth, hair production disorders, etc. Scarring alopecia may mean that it appears in various forms due to various causes, such as hair loss caused by lupus, idiopathic folliculitis, lichen planus pilaris, hair loss caused by burns and trauma.

In the present invention, the types of hair loss include scarring alopecia in which hair is not regenerated due to the destruction of hair follicles due to scarring, and non-scarring alopecia in which hair is regenerated after the symptomatic site is razed by maintaining hair follicles without forming scars. Scarring alopecia is caused by trauma, burns, leprosy or bacterial infection, and non-scarring hair loss includes alopecia areata, hair growth, telogen effluvium, drug-induced alopecia, secondary syphilis, dermatophytosis, endocrine disorders, and dermatomyositis. which is caused by, etc.

The term "prevention" of the present invention refers to preventing something or a phenomenon from occurring, that is, preventing hair loss from occurring, and a product that prevents hair loss along with hair growth is called an anti-hair loss agent. In addition, it is divided into a hair growth agent that nourishes the hair roots to grow hair, a hair growth agent that promotes blood circulation in the scalp to help prevent hair loss, and a hair growth agent that turns thinned vellus hair into healthy terminal hair.

In the present invention, the target of application of the anti-hair loss agent means that the focus is on scarring hair loss. Among scarring alopecia, androgenetic alopecia, in which male hormones act as an important etiology, accounts for about 80% of all hair loss symptoms. Genetic factors, the concentration of androgen, a male hormone in the blood, and a high concentration of dihydrotestosterone (DHT: dihydrotestosterone), which binds to androgen receptors present in scalp hair follicles, are known to be the main causes. DHT regulates hair growth by binding to the androgen receptor in the scalp dermal papilla. At this time, the binding of DHT transmits a cell destruction signal to the gene of the keratinocyte cell and activates the apoptosis factors DKK-1 and TGF-beta1. This means that hair loss occurs due to the destruction of hair cells.

In addition, in the present invention, the activity of 5-alpha-reductase, an enzyme that catalyzes the irreversible reduction of testosterone to DHT with nicotinamide adenine dinucleotide phosphate (NADPH) as a hydrogen donor, is It has to do with hair loss. That is, DHT produced in this way inhibits protein synthesis around the hair follicle, thereby reducing cell proliferation of hair cells, shrinking scalp hair follicles, and converting thick and long healthy hair into thin and short hair to progress hair loss.

The term "hair growth" of the present invention refers to the growth of hair in hair follicles, and the hair refers to the hair roots and hair follicles of the head, hair, eyelashes, eyebrows, beard, armpits, pubic hair, and all parts of the body with hair roots and hair follicles. include

The term "stimulation" of the present invention refers to controlling the growth cycle of hair by supplying nutrients to the hair root so that the hair grows quickly. At this time, the activity of outer root sheath cells, including dermal papilla cells and hair follicle stem cells constituting hair follicles, and various cytokines and growth factors produced by these cells play an important role. In particular, regeneration of hair follicles and activation of stem cells are followed for periodic hair growth, which is achieved through activation of the wint/beta-catenin signaling pathway. In addition, growth factors such as vascular endothelial growth factor (VEGF), insulin-like growth factor-1 (IGF-1), and fibroblast growth factor (FGF) promote the growth phase of hair, and transforming growth factor (TGFb-1) , Epidermal growth factor (EGF), etc. means to regulate the hair growth cycle by inducing the catagen phase of the hair follicle.

Therefore, in the present invention, the hair loss prevention or hair growth promoting effect promotes dermal papilla cell proliferation by the fucosyllactose, inhibits the activity of 5 alpha-reductase, and promotes the activity of the wint/beta-catenin signaling pathway may be achieved by

[Preparation Example 1] Preparation of 2-fucosyllactose and 3-fucosyllactose

In general, in the production method of fucosyllactose, fucosyllactose has a large difference in content or components depending on the type of strain, microbial fermentation, etc., and its functional, nutritional and physiologically active characteristics can be varied accordingly. Therefore, in the present invention, this experiment was performed using 2-fucosyllactose and 3-fucosyllactose purchased from Kyowa, Japan as commercially more refined fucosyllactose.

[Test Example 1] Proliferative effect of dermal papilla cells

In order to determine the effect of 2-fucosyllactose and 3-fucosyllactose on the proliferation of human hair follicle dermal papilla cells (hereinafter referred to as HHFDPC), which are the main cells of hair growth, the proliferation capacity of dermal papilla cells was measured. Human dermal papilla cells were purchased from PromoCell, and the HHFDPC was supplemented with a culture medium additive (Supplement Mix; PromoCell, Heidelberg, Germany), 100 units/mL of penicillin, and 100 μg of streptomycin. Cell Growth Medium; PromoCell, Heidelberg, Germany) was cultured at 37°C and 5% CO ₂ conditions. Specifically, after culturing HFDPC, it is inoculated into a 96-well plate (1.5 x 10 ⁴ cells/well), and incubated at 37°C for 24 hours in a 5% CO ₂ incubator, and the 4th to 6th subcultured HFDPC Cells were used for this test.

Dimethylsulfoxide (DMSO) diluted 1:1000 in DMEM (Dulbecco's modified Eagle's medium) containing 1% fetal bovine serum (FBS), penicillin 100 unit/mL and streptomycin 100 μg 1 ng/mL bFGF to the cultured cells As a control, 0.1 μg of minoxidil was used as a positive control, and 2-fucosyllactose (Example 1) and 3-fucosyllactose (Example 2) were treated at 0.1, 0.5, and 1 μg concentrations for each concentration, respectively. It was cultured again for 48 hours under the conditions of 37° C. and 5% CO ₂ (Table 1). After 72 hours, the cell culture supernatant was removed by centrifugation, washed once with PBS (Phosphate Buffer Saline) solution, and MTT (3-[4,5-dimethylthiazol-2-yl]-2 dissolved in 1 mg/mL ,5-diphenyltetrazolium bromide) reagent (Sigma, USA) was diluted 10 times, mixed with the medium, treated, and incubated for 1-2 hours, after which the MTT reagent was removed. When formazan crystals are observed in each well, 200 μl of DMSO per well is added and gently shaken for 30 minutes in a light-shielded state to dissolve the formazan crystals. The degree of cell proliferation was evaluated. CCK-8 was treated in a culture solution at a ratio of 1:10 and incubated for 1 hour, and then the absorbance at 450 nm was repeatedly measured three times using a spectrophotometer for each well, and the average of the absorbance values was calculated.

Table 1

The measurement results of the dermal papilla cell proliferation rate are shown in Table 1, and the results confirm that the dermal papilla cell proliferation effect is shown in all treatments at the concentrations of 0.1, 0.5, and 1 μg, respectively, for Examples 1 and 2. . Both Example 1 (130.48%) and Example 2 (128.71%) showed the same level of dermal papilla cell proliferation as Minoxidil (129.37%) even at the same 0.1 μg treatment concentration as the positive control minoxidil, Example 1 and 2 The difference in dermal papilla cell proliferation rate between livers was almost similar and did not show a significant difference. In addition, it was shown that the pattern of dermal papilla cell proliferation rate was not significantly different from the result of 0.1 μg treatment concentration even at the treatment concentrations of 0.5 and 1 μg for Examples 1 and 2, respectively.

Accordingly, it can be confirmed that both 2-fucosyllactose and 3-fucosyllactose have similar effects to minoxidil in promoting dermal papilla cell proliferation.

[Test Example 2] Inhibitory effect of 5-alpha-reductase activity

In order to evaluate the activity of 5 alpha-reductase in dermal papilla cells, dermal papilla cells were dispensed at 0.8 x 10 ⁶ cells/dish in a 60 mm cell culture dish. After 24 hours of culture, the existing culture medium was removed, and no additives were added (0 mg/mL) as a control for each dish, finasteride (1 mg/mL) as a positive control, Examples 1 and 2 (1 mg/mL) were treated, respectively, and exchanged again with the culture medium containing each of them, and cultured for 24 hours. After culturing, the existing culture medium was removed, washed with 1 x PBS, and treated with Trypsin/EDTA to make each single cell. After centrifugation, the cells were lysed using an extraction buffer (880 mM Sucrose, 1.5M CaCl ₂ ), and then the supernatant obtained by centrifugation was taken and used as a crude enzyme solution for the measurement test of 5-alpha-reductase activity inhibition ability. used The measurement and analysis method calculated the activity of 5-alpha-reductase by measuring the change in the amount of NADPH, a substrate used when testosterone is converted to dihydrotestosterone, by absorbance, and the crude enzyme solution (protein 35 μg), 20 μM testosterone (Sigma, USA) and 320 μM NADPH (Sigma, USA) were mixed and incubated for 30 minutes, and then the absorbance of the mixture was measured at 340 nm using a spectrophotometer to obtain 5 alpha -The activity of the reductase was analyzed.

Table 2

As shown in Table 2, when finasteride, known to inhibit the activity of 5-alpha-reductase, was treated at a concentration of 1 mg/mL, the relative activity was 74.26±2.81%, whereas the treatments of Examples 1 and 2 were shown. The activity of 5 alpha-reductase in one test group was 73.37 ± 1.45% in Example 1 and 74.56 ± 1.32% in Example 2, respectively. It can be seen that Examples 1 and 2 inhibit the activity of 5-alpha-reductase almost similar to finasteride.

Accordingly, it can be confirmed that both 2-fucosyllactose and 3-fucosyllactose have almost similar effects to finasteride in inhibiting the activity of 5-alpha-reductase.

[Test Example 3] Wint/beta-catenin signaling pathway activation effect

The method for measuring the activation level of dermal papilla cells, which are critically involved in hair follicle formation and regeneration, starts with a protein called Wnt, which is known to play an important role in maintaining and activating genes expressed during the growth of the hair cycle. Beta-catenin/TCF (T-cell factor) was measured using the TCF reporter luciferase system, which is a method for evaluating the activation of the wint/beta-catenin signaling pathway that is transferred to transcription factors.

As for human dermal papilla cells (HHFDPC), HFDPC cells cultured in the same way as in Test Example 1 were used in this experiment, and Wnt3a protein was used as a positive control to activate the wint/beta-catenin signaling pathway, and as a negative control. used DMSO. About 3x10 ⁴ of the Wnt reporter HEK293A cells were dispensed into each well in a 96-well plate, and 18 hours later, Example 5 was treated at a concentration of 5 μg, 10 μg, and 20 μg, respectively. Then, Wint reporter analysis was performed according to the protocol using Promega's Luciferase assay kit, and Wint/beta-catenin promoter activity was measured using PerkinElmer's luminometer Victor.

As shown in Figure 1, in Examples 1 and 2, compared to the untreated negative control group, the wint / beta-catenin signal was amplified by about 8.58 and 8.61 times, respectively, and did not show a concentration-dependent pattern, but at 20 μg / mL It was confirmed that there was a repeatable effect near the concentration. It can be seen that both Examples 1 and 2 exhibit similar effects to the positive control Wnt3a protein (8.6 times) binding to the direct receptor of wint/beta-catenin.

Therefore, both 2-fucosyllactose and 3-fucosyllactose promote the activity of the wint/beta-catenin signaling pathway, which is a hair growth promoting signal of hair follicle stem cells, and activate TCF transcription factors, thereby having excellent hair growth promoting effects. can confirm.

From the results of Test Examples 1, 2, and 3 above, both 2-fucosyllactose and 3-fucosyllactose have an effect of promoting proliferation of dermal papilla cells, an effect of inhibiting the activity of 5-alpha-reductase, and a beta-catenin signal. It was confirmed that the activation promoting effect of the delivery pathway was excellent.
